which corresponds to our definition of \(k\) -th order statistic eq:kths when \(k=2\) .
As the quantum information theoretic counterpart of heat
capacity, the capacity of entanglement is known to capture the deviation from the maximal entanglement [1]}, [2]}. The mean of entanglement capacity under the Hilbert-Schmidt ensemble has been recently computed in [3]}. For the fermionic Gaussian ensemble, we compute the exact average capacity when the subsystem dimension differences are \(a=0,1,2,3\) .
